An openly LGBT+ pony, huh? Wouldn't that just be something.
Yeah, they could do it, and I'd be the last to complain if they did, but I'm a-ok if they chose not to. There's still too much of a stigma against the LGBT+ mixed with kids and that'll take some time to wear off. The last thing Hasbro wants is to be the first to open that can of worms, you know? Because then MLP wouldn't be remembered as a cartoon about little pastel ponies learning about friendship, it'd be the first show to flat-out show an LGBT character. People would make a bigger deal out of it than it really needs to be.
So I'm cool with MLP sticking with the safe, politically safe content. Maybe G5 will have more luck; who knows?
